If you searched for a peptide reconstitution calculator and landed here, this is the honest answer rather than the tool. We removed ours deliberately, and the reasoning is worth more than the arithmetic was.
A reconstitution calculator is only arithmetic, and that is the problem. On its own it implies the hard part is the mixing math, when the hard part is whether a substance should be prescribed to you at all, by whom, from what source, and after which labs. A number on a screen answers none of that.
Compounded preparations fall under section 503A of the Federal Food, Drug, and Cosmetic Act. The FDA maintains interim lists of bulk drug substances and sorts nominated substances into categories while it evaluates them. The category that matters here is the second.
“Bulk drug substances that may present significant safety risks have been placed in category 2 under the interim policies.” U.S. Food and Drug Administration, Certain Bulk Drug Substances for Use in Compounding that May Present Significant Safety Risks. Content current as of 22 April 2026.
The concerns the agency weighs for substances of this class are described in general terms: identity and purity, salt form, aggregation and degradation products, sterility and endotoxins, immunogenicity, and the limited human clinical data available for many of them.
That list is not static. In April 2026 the FDA removed a group of peptide substances from category 2 after their nominations were withdrawn, and scheduled advisory committee review to consider whether any should move onto the list a compounding pharmacy may actually use. Removal from category 2 is not approval and it is not permission. It means the evaluation changed state.
South Carolina adds a layer. The South Carolina Board of Medical Examiners has issued guidance restricting non-FDA-approved peptides, and it reaches past prescribing to advising, recommending, and supplying. A practice in this state publishing a public dosing utility stands very close to that line, whatever the disclaimer underneath it says.
You will notice this page names no peptides. That is deliberate, and it is the same reason the calculator is gone.
If you are already a Solcara patient, your dose, frequency, and preparation instructions come from your clinician and the pharmacy label, not from a web page. If anything is unclear, call us rather than calculating.
If you are not a patient and you wanted a calculator because you obtained something without a prescription, the honest advice is to speak with a clinician first. The mixing math is the least consequential decision in that sequence.
Book a consultation →Educational, not medical advice. This page describes a regulatory framework that changes often and is current as of the FDA page cited above. It does not recommend, endorse, or supply any compounded substance. Solcara Health provides medically supervised care in Mount Pleasant and Charleston, South Carolina, with laboratory work before any prescription.
